• Direct, indirect addressing modes for data accessing

• 8-bit real time clock/counter (Timer0) with 8-bit programmable prescaler

• Internal Power-on Reset (POR)

• Built-in Low Voltage Detector (LVD) for Brown-out Reset (BOR)

• Power-up Reset Timer (PWRT) and Oscillator Start-up Timer(OST)

• On chip Watchdog Timer (WDT) with internal oscillator for reliable operation and soft-ware watch-dog

enable/disable control

• Two I/O ports IOA and IOB with independent direction control

• Soft-ware I/O pull-high/pull-down or open-drain control

• One internal interrupt source: Timer0 overflow; Two external interrupt source: INT pin, Port B input change

• Wake-up from SLEEP by INT pin or Port B input change

• Power saving SLEEP mode
